Notes:

(*)
The current patent numbering system began with a patent issued on July 13, 1836. Prior
to that date, an estimated 9,957 patents had been issued. Defensive Publications (T) and Improvement
patents (AI) are not included in this table.

(**)
Reissue patents were not separately numbered until 1838.

Some patent numbers, as displayed in the table, are 7 characters with the
numeric portion padded with leading zeroes.

Some numbers within a series may be unused. Therefore, the number of patents
granted during a year cannot be determined by simply subtracting the number of
the first patent issued in one year from the number of the first patent
issued in the next year. The user should note that while the data in this table have
been checked, it still is possible that inadvertent errors remain.

A detailed Patent Technology Monitoring Team report, titled
Issue Dates and Patent Numbers Since 1836, which contains first patent
numbers and the day of issue for patents issued since 1963, also may be of interest.
